Redox reaction: HNO3 +S → H2SO4 + NO
Half-reactions with balanced electrons:
6e + 2HNO3 → 2NO
SH2SO4 +6e
Which is the final balanced redox equation?
HNO3 + 2S → 2H2SO4 + NO
HNO3 + 2S + 3e → 2H2SO4 + NO + 6e
2HNO3 +S →H2SO4 + 2NO
2HNO3 + S + 6e → H2SO4 + 2NO + 6e

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
